so cut the multiple shingle-strips as to avoid waste of material,

A further object is to construct the two longitudinal edges of thestrips symmetrically in such 'a manner thatin case one or moreshingle-projections should be torn or broken oil at one edge of a strip,the latter canbe reversed to conceal the broken edge and present acomplete and intent shingle edge at lits lower exposed portion, thusavoiding the necessity of discarding such broken shingle strips andeffecting an iniportant saving.

Another object of the invention is the 1inL provement of the shinglestrips with a View ot' insuring absolutely tight joints at their ends.

ln the accompanying drawings.:

Figure 1' is a fragmentary plan view of several courses of the improvedshinglestrips.- Figure 2 is a plan view of a sheet of material, such asready roofing, showing the method of cutting the strips. .Figure 3 is aperspective view of ne of the stripst Figure 4 1s atransverse .erticalsection on line 4&4, Fig. l. Figure 5 is a similar section, showing adefective or worn out shingle withdrawn. Figures 6 and 7 are horizontal.sections on the .correspondingly numbered lines in Fig. l. y

Similar characters of lreclerence indicate corresponding partsthroughout the several views. l

s shown in the drawings, the iinproved A shingle-strip is serrated atboth longitudinal edges to form a row of substantially V- shapedprojections l0 at each edge, representing a corresponding number ofshingle units. In the example shown, each strip has four completeshingle-projections at one edge, while its other edge is formed withthree complete projectionsV and two hall? projections arranged atopposite ends there- Serial to. 501,748.

of, these half-projections forming complete projections when laid`against adjoining strips having similar half-projections.r rlhe stripsmay however be provided with any other suitable number of projections,if desired. The projections at one edge of each strip arev staggeredwith reference to those ,of the other edge, or, in Iother words, theprojections' of one edge are arranged directly opposite thesubstantially ii-shaped recesses ll ot the other edge.

l By constructing the shingle-strips in this manner, Va number or themcan he cut from a single sheet of ready rooting orl other ap,- propriatematerial without waste,iloy severing the sheet along the dotted zig-zaglines l2 in Fig. 2, these lines extending across the sheet at intervalscorresponding to the ver tical dimensions of the strips.

Each shingle strip is preferably -cut away at its ends', adjacent to oneof its longitudinal edges, in the forni of angular notches or recesses13. ,When such. strips are laid end to end on a roof, the vertical edges14 of their opposing notches abut against each other, as shown in Figs.l and-7, while' the remaining unnotched end portion of one stripoverlaps the correspondingvportion of the adjoining strip, as shown inFigs. 1 and l 6, producing tight joints which eiiectually preventleakage at these points. Theedges 14C form" stops which limit the extentof over'- lap of the shingle-strips.

As both edges of the strips have shingle projections of uniform contour,the strips can be lai-d to expose either edge. This reversible featurehas the advantage that in the event of a projection being broken' at oneedge, the strip can be reversedto con'- -ceal the broken edge under theoverlying course of strips, thus avoiding waste of such partlybrokenstrips.

The shingle strips are usually laid in three courses, as shown .in Figs.l and 4:. The construction of this improved 4shingle-strip is Such thatif one should be blown ott' by a v.heavy wind, the two remainingcourses'or thicknesses providev sui'licientrotection against leakageuntil it can Vloe rep aced, and

this is also, ,the case where one or more shingle points or projectionsare broken o, as above mentioned.

'In laying the shingle-strips, the can be readily and properly spacedone a ove an- 0' other by 'bringing the points or projections of" thestrips in register with the apexes of lcorresponding edge of anadjoining shingle- 15 the recesses of the underlying course ot strips. l

I claim as my invention:

l. A reversible shingle-strip, having e row of projections at each ofits longitudinal edges forming intervening recesses., the projections atone edge of the strip being disposed directlyopposite the recesses ofthe opposite edge, and the projections at both edges being of uniform.shape, the strip being provided in each end, adjacent to one of itslongitudinal edges9 with a notch Whose vertical edge is adapted to abutagainst the 2. rllhe combination of adjoining shinglestrips, each havinge row of shingle-projections along one of its longitudinal edges, andnotches in its ends adjacent to one of such edges, the vertical edges ofthe notches of adjoining shingle-strips abutting `against each other,While the end portion of one strip overlaps the corresponding portion ofthe adjoining strip, forming partly a. butt joint and partly e lapejointat the adjoining ends of the strips' JACUB OTT.
